Embodiment Construction

[0010] The lead-out wire 11 of the measuring end is welded together with the measuring end 6, see the screw-in diagram figure 2 . The temperature-resistant and insulating sleeve 7 is put on the outside of the lead wire 11 at the measuring end. Put the temperature-resistant and pressure-resistant insulating sleeve 8 on the outside of the temperature-resistant and resistant insulating sleeve 7 . The lead-out line 1 of the compensation end is welded together with the compensation end 5, and at the same time, they are put on the temperature-resistant and insulating sleeve 7. At this time, the temperature-resistant and pressure-resistant insulating sleeve 8 is between the compensation end 5 and the measuring end 6. The temperature-resistant and insulating sleeve 9 is set outside the lead wire 1 of the compensation end, and the temperature-resistant and voltage-resistant insulating tube 4 is set outside the temperature-resistant and insulating tube 9 . Put the common end 3 on the...

Abstract

The present invention belongs to the field of measurement technology, and is especially one three terminal water level electrode comprising compensating terminal lead, common terminal, heat resisting and pressure resisting insulating tube, compensating terminal, measuring terminal, and measuring terminal lead. The measuring terminal lead is coated with one heat resisting and pressure resisting insulating tube, and the compensating terminal lead around the heat resisting and pressure resisting insulating tube is coated with one other heat resisting and pressure resisting insulating tube. The present invention is superior to two terminal electrode water level meter, which has greater measurement error caused by pollution, scaling, etc.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to an electrode for measuring water level, in particular to a three-terminal water level electrode. technical background [0002] Measuring the water level by means of an electric contact water level gauge is the most widely used means of water level measurement at present, especially in the field of thermoelectricity, it is even more important to measure the water level of the steam drum. The main components of the electric contact water level gauge include the electrode, the measuring cylinder and the secondary instrument. The electrode is fixed on the measuring cylinder. The electrode of the electric contact water level gauge is the extraction part of the water level information. The structure and characteristics of the electrode have a great influence on the performance of the electric contact water level gauge. Impact is critical. [0003] However, the electrodes of the elec...
